Experimental and Implementation of a 15 × 10 TEG Array of a Thermoelectric Power Generation System Using Two-Pass Flow of a Tap Water Pipeline Based on Renewable Energy

Abstract

At the present time, the entire world is suffering from global climate change due to emissions caused by the combustion of fossil fuels. Thus, it is necessary to look for alternative power sources to generate clean electrical energy. Thermoelectric generators (TEG) are one of these alternatives. They convert thermal energy into useful electricity. There are many thermal energy sources such as hot water pipes. The current paper aims to convert waste heat from solar water-fed hot water pipes into electricity using a TEG panel made from 15 × 10 TEG modules. A pipe through which hot water flows serves as the hot side of the panel. The cold side of the panel is cooled using normal tap water. The maximum recorded temperature difference is 42.35 °C which yields an open-circuit voltage of 15.3 V. The maximum efficiency of the panel is 2.1% with an average energy production of 1.435 kWh. This proposed novel TEG panel system can be used continuously day and night. This is in contrast to a solar system, which operates only during the day, as it relies solely on solar radiation.

Design of a battery charging system fed by thermoelectric generator panels using MPPT techniques

“…There are 15 TEG lines are connected in parallel for a 15×10 TEG panel. The TEG panel is based a previously reported practical design of a 150 TEG panel [21]. The results of system input power (Pi) during startup are shown in Fig.…”

“…There are 15 lines connected in parallel. Thus, the total number of TEGs in the proposed panel is 150 [21].…”

Influence of Surrounding Air Temperature and Humidity upon the Performance of a Gas Turbine Power Plant

“…Nevertheless, the validity of the software was assessed before proceeding to the main analysis. OriginPro 2021b was used to plot various figures [30,31]. The obtained results were compared with a base-case cycle.…”

“…Furthermore, in [16], the utilization of the MPPT technique with renewable energy sources is not done. Accordingly, such techniques can be used with promising non-traditional renewable energy systems, such as thermoelectric modules [34], [35].
